The STRC Traxxas TRX-4 One-Piece Servo Mount/Chassis Brace is a one-piece CNC machined aluminum option that will greatly reduce the flex in the servo mounting area. This will allow your servo to transfer more power to the steering linkage, instead of being lost due to flex. The part also serves as a front chassis brace to reduce front chassis twist. Plus, they are available in a variety of colors to make your TRX-4 more unique.
